In addition, as posters have alluded to upthread, a lot of them are portrayed as being, frankly, not terribly bright (or at least uneducated).
Dumb supervillains tend to be motivated by greed – and, sometimes, just enjoy breaking things and beating people up. Intelligent supervillains tend to be motivated by seeking power, fame, revenge, etc.
Which is weird, because there are so many legal, non-heroic ways to use superpowers. Superstrength? You’re the star of the Gotham moving industry. Flight? You’re the most high-demand courier in the country. Underwater powers? Every marine biologist and oil country in the world want to work with you. And so on. But I guess the super industrial complex has no time for the working-joe enhanced.
TBF…some criminals in Marvel often get away with it. That’s how the story lines move along. It’d get boring if every story ended with the heroes winning.
Not to mention multiple earths where some have the bad guys controlling everything and the heroes are in hiding.
Magneto seems to have done well. Thanos sure did for a very long time. Too many to list but I hope that’s enough to get the point across.
And what about gray areas like Hulk or Deadpool or even Wolverine? They may not be evil but they are not exactly law abiding good citizens either (Wolverine maybe is…mostly).
It makes no sense except in the context of fiction, obviously. As an intellectual exercise we can justify it in lots of ways.
For example, we only see when the heroes succeed. Statistically, most crimes in the comic book universe are actually easy and extremely profitable, but the successes aren’t shown to the reader. This explains why minor criminals keep at it despite the risk, as well as how supervillains can afford their equipment, lairs, and bizarre, convoluted, and ridiculously expensive plots against the heroes.
Or just watch the Venture Brothers- there’s a whole system designed to keep heroes and villains fighting each other so that society can continue without too much disruption, and magic/superscience never becomes available to the public.
You might as well ask what motivates criminals in the real world. Prisons are full of three time losers who committed a third felony, despite having been caught in two previous felonies and several misdemeanors.
Author Michael Chabon (who wrote The Amazing Adventures of Kavalier and Clay) has likewise noted the irony that, despite fighting Nazis back in the Golden Age, superheroes as a concept are quite fascist. The basic idea that problems should be solved through physical strength, and that the “good guy” is the guy who is the strongest, the most powerful, the most physically impressive and dominant, is essential to the Nazi ideal.
I remember reading a non-Marvel/DC story that had a supergroup taking on a preening supervillain. He had his super HQ, legions of followers, multiple weapons of mass destruction, etc. He was every bit the stereotype, gloating over his victories, punishing lackeys for minor infractions, showing off his babelicious arm candy, and so on.
The last panel showed a lone missile that had gotten through his defences and was heading straight toward his command module, and he’s standing there with a forlorn look on his face and saying the words “I was just wanting to have a little fun” before getting obliterated.
One certainly would suspect that, on an Earth with numerous superpowered people, there’d be a demand for them in “mundane” professions. But, that doesn’t make for good comic book storytelling, I guess – who wands to read about Dolphin Dan who works as a marine biologist?
Way back in the early days of the Avengers, the group broke up because of the Hulk. Captain American started a new group, comprised of the villains Hawkeye, Quicksilver, and the Scarlet Witch. The Witch later went crazy and destroyed the universe or some such, but was rehabiliatated and led to a cycle that was shown in her tv series and the Dr. Strange movie.
The Avengers took in many former villains over the years, like the Black Widow and Wonder Man, and good-guy Hank Pym - he of the many identities - became a wife-beater, possibly because his mind was affected by growing and shrinking too much. Even loyal and faithful Jarvis betrayed the Avengers, although it was revealed he was under mind control. The Hulk has been at every point on the compass. You can find similar examples of being considered either a hero or villain in the DC world. Ultimate good guys like Captain America, demonized in Secret Empire, and Superman, as a dangerous alien, were villainized.
The whole Civil War saga pitted groups of superheroes against one another supporting or rebelling against the Superhuman Registration Act.
Mostly, my crack about the writers is the only truth. Tens, hundreds, of thousands of superhero stories have been written over 90 years. Plots get reused wholesale of necessity. But sometimes writers get permission to flip the world upside down and explore new consequences. There was a period in the 90s when the good guys were almost as morally dubious as the bad guys. Yeah, the good guys always win in some way in the end, but the absolute values of the 40s are long gone.
Now let’s talk of the probability of a small-time crook being found by Batman, who has to slowly patrol Gotham (Manhattan) and its 500 miles of streets looking for crime taking place in the back of brownhouses, and why crooks think they have a 99% chance of not being caught.
The OP is basically asking why writers keep reusing the same villains. It’s mostly because any franchise needs so damn many of them. For every superhero with a continuing series, you need dozens of different villains to keep him busy year after year, and that’s with using the same ones over and over again.
IRL or in the comics, folks become mooks when there’s not much other way to earn a living.
Maybe they hope to be promoted to Thug Leader I soon, but those promotions are hard to earn and the pole to climb is especially greasy. So of the fairly few folks with higher aspirations, most remain mooks. Or get killed or jailed along the way.
How many henchmen even have a name, let alone a recognizable face? How do we know they kept coming back for more? At least the old Batman show henchmen usually had their names printed on their shirts. I never saw anything like that in comic books.
